Hi Benson,

It's not as easy as it looks to do "intelligently".  While it is often
taught that methods should have a single entry point and exit point, not
many programmers adhear to this.  It is not at all uncommon to find return
statements in if-blocks and try-catch blocks.  Sometimes the exit logic can
get very convoluted.

I've always been partial to single exit logic.  I didn't become a fan until
trying to insert trace statements, just as you describe, in other people's
code.  It can be a nightmare.

Subject:  automatic trace insertion

Hi all,

I'm interested in automatically inserting log4j trace statements at the
beginning of all methods and right before the end of a method (return
statement or thrown exception).  I'm presuming most people have worked
on projects with extensive class libraries and it would be great if
there was a class parser that could intelligently insert log4j
statements automatically.  If there isn't anything out there like that,
does anyone know of a java class parser that can be used to do this sort
of thing?  Thoughts or ideas?  Thanks!
